I'm unsure of the Fire. In fairness I have a TouchPad and think that tablets are mostly useless.
I don't understand the Touch, though. With the regular Kindle the buttons to change pages are just under your thumb. With the Touch you have to move and swipe your thumb. I average several pages per minute, so that's a ton of thumb movement. Much, much nicer to just gently push the button.
I guess I'll have to see one in person.
Love my Kindle. Love the new one. Just not loving the Touch, and waiting to see on the Fire.
